LOCKING DEVICE FOR REMOVABLE BARREL- COVERS.

SPECIFICATION forming part of Letters Patent No. 470,519, dated March 8,1892. Application filed June 30, 1891. Serial No. 398,054- (No model.)

T at whom it 11mg concern.-

Be it known that I, JOHN G. TIFFANY, a citizen of the United States,residing at Xenia, in the county of Greene and State of Ohio, haveinvented certain new and useful Improvements in Looking Devices forRemovable Barrel-Covers, &c.; and I do hereby declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same. I

This invention relates to an improvementin devices for looking orsecuring barrel heads orlids to barrels which are used for the purposeof removing night-soil, garbage, slops, and all other offensive refuse,the object being to provide a simple, cheap, and efficient constructionfor this purpose and one which can be readily operated and not liable toget out of order.

The invention therefore consists, essentially, in theconstruction,arrangement, and combination of parts, substantially aswill be hereinafter described and claimed.

In the annexed drawings,- illustrating my invention, Figure 1 is a topview of the barrel lid or cover provided with my improved lockingdevice. Fig. 2 is a side elevation of a the same, showing the barrel andits cover in a locked position. Fig. 3 is a similar view,

' partly in section, showing more clearly the contain the garbage,night-soil,or other offensive matter, andB represents the cover or lid.The lid is provided with a cross-piece or handle C, which is preferablymade of wood and of any suitable length and shape. ,To this crosspiece 0is secured the locking plate or bar 0,

having the hooked ends 0 c, which engage with the plate D on the barrel,and are formed by bending the ends of the plate 0 downwardly at rightangles, then inwardly, as shown in Fig. 3. This bar or plate ispreferably made of metal. The parts 0 and C may be made integral, ifdesired. a a

Passing through the cross-plece O,lock1ngplate 0, and cover B isa bolt6, having its lower end screw-threaded,which screw-threaded end isadapted to be engaged by a nut e on the under side of the barrel-cover.The parts 0 and O are thus adapted to rotate on the cover B, so thatwhen the cover is placed upon the barrel the locking-plate may berotated until it comes into proper engagement with the plates D D on thebarrel A. The lid or cover B may be made beveled or Hat on itscircumferential edge. In the present example of my invention it is madewith a bevel, as shown in Fig. 3. A strip of rubber or other suitablepacking b may be secured to this edge for the purpose of moreeffectually preventing the escape of all offensive odors from the barrelinto the atmosphere.

Secured to the barrel A near the top and opposite to each other aremetal strips or plates D D. These plates are constructed, as shown inFig. 2, with inclined flanges or lips d d. These flanges are oppositelyinclined, so that when the locking-plate is rotated upon them the hookedends a 0 will travel up their respective inclines, and vice versa, whenit is I desired to remove the cover.

On the barrel-cover B is secured a lock link or plate E, having anupwardly-projecting lip or flange E bent at a small angle to the mainbody E. The plate E is provided with a longitudinal slot f,in whichworks a set-screw F, which passes down into the body of the barrel-coverand secures the lock-link in any desired position.

The operation of my improved locking device will be readily apparentfrom the foregoing description of the construction and arrangement ofthe several mechanical parts. When it is desired to secure the cover in.a

locked position, the operator will place the into the position shown inFig. 1 and by means of the set-screw F firmly clamp the same against thecross-piece 0, thus holding the barrel-cover B securely in position.This construction provides a very simple, efficient, and i cheap device,and in practical operation it will be found that all unpleasant odorsWhichmay arise from the contents of the barrel Will be eifectuallyprevented from escaping.

Numerous details may be made in theprecise construction of themechanical devices herein shown and described without departing from thespirit of my invention, and I reserve the liberty of making. any suchchanges as may come Within the scope of my present improvement.

Having. thus described my invention, What I- claim as new, and desire tosecure by Letters Patent, is-- The combinatiomwith the plates DD,prolocking-plate having hooked ends 0 0, con-' structed substantially asdescribed and adapt- .ed to engage the flanges (1 cl, and the lock-linkE, provided withflange E, slot f, and setscrew F, substantially asdescribed. I

In testimony whereof I affix my signature in presence of two witnesses..

JOHN C. TIFFANY.
